These operations can be performed using a single low voltage to V supply. On power-up the memory defaults to its read mode where it can be read in the same way as a ROM or EPROM. The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased. Each block can be protected independently to prevent accidental program or erase commands from modifying the memory. Program and erase commands are written to the command interface of the memory. An on-chip program/erase controller simplifies the process of programming or erasing the memory by taking care of all of the special operations that are required to update the memory contents. The end of a program or erase operation can be detected and any error conditions identified. The command set required to control the memory is consistent with JEDEC standards. The blocks in the memory are asymmetrically arranged, see Figure 5 Block addresses x 8 and Figure 6 Block addresses x The first or last 64 Kbytes have been divided into four additional blocks. The 16-Kbyte boot block can be used for small initialization code to start the microprocessor, the two 8-Kbyte parameter blocks can be used for parameter storage and the remaining 32-Kbyte is a small main block where the application may be stored. Chip Enable, Output Enable and Write Enable signals control the bus operation of the memory. They allow simple connection to most microprocessors, often without additional logic. The memory is offered in SO44, TSOP48 12 x 20 mm and TFBGA48 6 x 8 mm pitch packages. The memory is supplied with all the bits erased set to Figure Logic diagram VCC 19 A0-A18 15 DQ0-DQ14 W E G RP BYTE M29W800DT M29W800DB AI05470B 6/52 M29W800DT, M29W800DB Table Signal names Signal A0-A18 DQ0-DQ7 DQ8-DQ14 E G W RP RB BYTE VCC VSS NC Address inputs Data inputs/outputs Data inputs/outputs Data input/output or address input Chip enable Output enable Write enable Reset/block temporary unprotect Ready/busy output not available on SO44 package Byte/word organization select Supply voltage Ground Not connected internally Figure SO connections Direction Inputs I/O I/O I/O Input Output Input RP A18 A17 A7 A6 A5 A4 A3 A2 A1 A0 E VSS G DQ0 DQ8 DQ1 DQ9 DQ2 DQ10 DQ3 DQ11 11 M29W800DT 34 12 M29W800DB 33 W NC A8 A9 A10 A11 A12 A13 A14 A15 A16 BYTE VSS DQ7 DQ14 DQ6 DQ13 DQ5 DQ12 DQ4 VCC AI05462b 7/52 Description Figure TSOP connections M29W800DT, M29W800DB A15 1 48 A16 BYTE Ordering information Ordering information M29W800DT, M29W800DB Note: Table Ordering information scheme Example: Device type M29 Operating voltage W = VCC = to V Device function 800D = 8-Mbit x 8/x 16 , boot block Array matrix T = top boot B = bottom boot Speed 45 = 45 ns 70 = 70 ns 90 = 90 ns Package M = SO44 N = TSOP48 12 x 20 mm ZE = TFBGA48 6 x 8 mm, mm pitch Temperature range 6 = to 85 °C 1 = 0 to 70 °C Option T = tape & reel packing E = lead-free package, standard packing F = lead-free package, tape & reel packing M29W800DB 90 N 6 T For a list of available options speed, package, etc. or for further information on any aspect of this device, please contact your nearest Numonyx Sales Office. 38/52 M29W800DT, M29W800DB Appendix A Block address table Table Top boot block addresses, M29W800DT # Size Kbytes Address range x 8 FA000h-FBFFFh F8000h-F9FFFh F0000h-F7FFFh E0000h-EFFFFh D0000h-DFFFFh C0000h-CFFFFh B0000h-BFFFFh A0000h-AFFFFh 90000h-9FFFFh 80000h-8FFFFh 70000h-7FFFFh 60000h-6FFFFh 50000h-5FFFFh 40000h-4FFFFh 30000h-3FFFFh 20000h-2FFFFh 10000h-1FFFFh Block address table Address range x 16 7E000h-7FFFFh 7D000h-7DFFFh 7C000h-7CFFFh 78000h-7BFFFh 70000h-77FFFh 68000h-6FFFFh 60000h-67FFFh 58000h-5FFFFh 50000h-57FFFh 48000h-4FFFFh 40000h-47FFFh 38000h-3FFFFh 30000h-37FFFh 28000h-2FFFFh 20000h-27FFFh 18000h-1FFFFh 10000h-17FFFh 08000h-0FFFFh 39/52 Block address table M29W800DT, M29W800DB Table Bottom boot block addresses, M29W800DB # Size Kbytes Address range x 8 E0000h-EFFFFh D0000h-DFFFFh C0000h-CFFFFh B0000h-BFFFFh A0000h-AFFFFh 90000h-9FFFFh 80000h-8FFFFh 70000h-7FFFFh 60000h-6FFFFh 50000h-5FFFFh 40000h-4FFFFh 30000h-3FFFFh 20000h-2FFFFh 10000h-1FFFFh 08000h-0FFFFh 06000h-07FFFh 04000h-05FFFh Address range x 16 78000h-7FFFFh 70000h-77FFFh 68000h-6FFFFh 60000h-67FFFh 58000h-5FFFFh 50000h-57FFFh 48000h-4FFFFh 40000h-47FFFh 38000h-3FFFFh 30000h-37FFFh 28000h-2FFFFh 20000h-27FFFh 18000h-1FFFFh 10000h-17FFFh 08000h-0FFFFh 04000h-07FFFh 03000h-03FFFh 02000h-02FFFh 40/52 M29W800DT, M29W800DB Common flash interface CFI Appendix B Common flash interface CFI The common flash interface is a JEDEC approved, standardized data structure that can be read from the flash memory device. It allows a system software to query the device to determine various electrical and timing parameters, density information and functions supported by the memory. The system can interface easily with the device, enabling the software to upgrade itself when necessary. When the CFI Query command is issued the device enters CFI query mode and the data structure is read from the memory. Table 22, Table 23, Table 24, Table 25, Table 26 and Table 27 show the addresses used to retrieve the data. Erase suspend latency time typical and maximum and data retention parameters added to Table 6 Program/erase times and program/erase endurance cycles, and typical after 100k W/E cycles column removed.
